The bulk of this codex contains Hugh of Saint Victor's De sacramentis fidei christianae (10r-147r). Preceding it are two short treatises on the Antichrist (Ps.-Augustine 1r-6v and Peter Damian 6v-10r), and after it comes a collection of opinions of and excerpts from Hrabanus Maurus' De universo. With very few exceptions, 1-44 are palimpsests. The pages towards the end have many large holes and tears or are partially excised; one folio, between 10 and 11r, is missing entirely. The writing is characterized by several changes of ink and hand, and the page ruling is not uniform. Except for simple red and black initials and rubricated lines, there is no book decoration whatsoever. A pair of marginal notes appear on 112v. Although the codex contains no univocal indication that it was produced in Engelberg, a few similarities with the volumes produced under Abbot Frowin (1143-1178) suggest it. (grd)
